Suitable covered storage space shall be provided for the safe storage of the glass sheets. In removing glass sheets from crates, great care shall be taken to avoid damages. The glass sheets shall be lifted and stored on its long edges against a vertical wall or other support with the first sheet so placed that its bottom edge is 25 mm from the vertical support.
The stacks shall be of not more than 25 panes and shall be supported at two points by fillets of wood at mm from each end. The whole stack shall be as close and as upright as possible. Different sizes and types of each of these boards shall be stacked separately. The board shall be stacked on a flat platform on which a wooden frame shall be constructed with 50 mm x 25 mm battens in such a way that it will give support to all four edges and corners of the boards with intermediate battens placed at suitable intervals to avoid warping.
The glass sheets of different sizes, thickness and type shall be stacked separately. The distance between any two stacks shall be of the order of mm. The boards shall be stacked in a solid block in a clear vertical alignment. The top sheet of each stack shall be suitably weighed down to prevent warping wherever necessary. While planning the layout. IS No. Cement bags shall be stacked off the floor on wooden planks in such a way as to keep about mm to mm clear above the floor.

Bricks of different classifications from strength consideration and size consideration such as. In general. If it is required to be stored for a longer period not exceeding 2 months it may be kept in a dry and closed godown. In case quicklime is stored in a covered shed. If unavoidable. For proper inspection of quality and ease in counting. Care shall be taken to see that the waterproofing membrane is not damaged any time during use.
The heaps shall be stored on a suitable platform and covered by waterproof membranesuch as polyethylene to avoid direct contact with rain or being blown away by wind. It should be slaked as soon as possible before deterioration sets in. These shall not be dumped at site. Clear distance between adjacent stacks shall not be less than 0. Proper access shall be provided for the replacement of silos. It should be stored in a building to protect and to minimize the lime from dampness warehouse deterioration.
After taking out the required quantity of cement.
Unloading of building bricks or handling in any other way likely to damage the corners or edges or other parts of bricks shall not be permitted. When air movement is reduced to a practical minimum. Fly ash in bags shall be stored in stacks not more than 10 bags high. These shall be stacked on plane level ground having a floor of bricks or a thin layer of lean concrete. All blocks should be water cured for 10 to 14 days and air cured for another 15 days. Fine aggregates shall be stacked in a place where loss due to the effect of wind is minimum.
The suggested sizes for stacks are as follows: Height of the stack shall not be more than one metre. Wall and Roof Tiles 4. The height of the stack shall not be more than 1. Breadth 2. The lintel and sill blocks shall be unloaded as individual component by holding them near the ends. In case blocks cured for less than 28 days are received. On a large job it is desirable to construct dividing walls to give each type of aggregates its own compartment.
If such a surface is not available. Wall and Roof. In the stack. Tiles when supplied by manufacturers packed in wooden crates. The blocks shall be stacked as per 4. The crates shall be opened one at a time as and when required for use.
During unloading. The length of the stack shall not be more than 3. It is preferable to transport these at the site on platform trolleys. Fly ash in bulk quantities shall be stored in stack similar to fine aggregates as specified in 4.
In case where separate crossers are not available smaller sections of the available structural timber may be employed in their place.
The crossers in different layers shall be in vertical alignment. In case. The waffle units shall be stacked upside down as individual units. It is desirable that ends of bars and sections of each class be painted in distinct separate colours. R C planks. Channel units. The most suitable width and height of a stack are recommended to be about 1. The various members shall preferably be stored separately in different lengths. The components shall be handled by holding at specified points so that the stresses due to handling are minimized.
A side view of such a stack is shown in Fig. The crossers shall be sound wood. Distance between adjacent stacks is recommended to be at least mm.
The longer pieces shall be placed in the bottom layers and shorter pieces in the top layers but one end of the stack shall be in true vertical alignment. R Cplanks. In any layer. The distance between any two adjacent stacks shall not be less than mm. The R C joists. Heavy weights. In case the stacking with the help of battens is not possible.
Asbestos cement sheets of same variety and size shall be stacked together. Damaged sheets shall not be stacked with sound materials.
Windows and Ventilators I 4. It shall be stored above ground level by at least mm upon platforms. These shall not be allowed to stand for long in this manner before being fixed so as to avoid the door frames getting out of 4.
It is desirable to coat reinforcement with cement wash before stacking to prevent scaling and rusting. When materials of different sizes.. The door shutters shall be stacked in the form of clean vertical stacks one over the other and at least 80 mm above ground on pallets or suitable beams or rafters. The wet material may be dried by stacking in shade with battens in between adjacent boards with free access of dry air generail.
In coastal areas or in case of long storage suitable protective coating of primer paint shall be given to prevent scaling and rusting. The shutter stack shall rest on hard and level ground. The aluminium sections shall not be pulled or pushed from the stack nor shall be slided over each other.
